OPERATING METHOD FOR A MOTOR VEHICLE DRIVING UNIT

摘要

PCT No. PCT/EP97/06047 Sec. 371 Date Mar. 25, 1999 Sec. 102(e) Date Mar. 25, 1999 PCT Filed Nov. 3, 1997 PCT Pub. No. WO98/21464 PCT Pub. Date May 22, 1998In motor vehicles fitted with overlay steering mechanisms comprising a transmission (2) and a steering transmission (4), substantial amounts of torque flow from the transmission inlet (12) to the steering transmission (4) when cornering. This results in a loss of speed during cornering. According to the method described, the torque flow to the steering transmission (4) is preferably automatically compensated by higher prime mover torque. Driving performance can be enhanced during cornering without needing to design the transmission (2) for higher input torque. The principle disclosed in the invention can be used for other applications.
